JET AND SPRAY NOZZLE.

SPECIFICATION forming part of Letters Patent No. 338,602, dated February23l 1886.

Application filed August 14, 1885. Serial No. 174,393. (No model.)

To all whom t may concern.-

Be it known that I, EDWIN It. ToMLiNsoN, a citizen of the United States,residing at Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in J etand Spray Nozzles; and I do hereby declare the following to be a full,clear, and exact description of the invention7 such as will enable oth-1o ers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain 'novel and useful improvements in jetand spray nozzles, and has for its object to provide a device of thisdescription by means of which the water passing th rough may be causedto issue either in a solid jet or in the form of diverging spray; andwith these ends in view my invention consists in certain details ofconstruction and combination of elements hereinafter fully explained,and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertainsmay more fully understand its construction and operation, I will proceedto describe the same in detail, referring` by letter to the accompanyingdrawings, forming a part of this specification, in which- Figure l is acentral longitudinal section of my device, showing it arranged to emit asolid jet; Fig. 2, a partial sect-i011 similar to Fig. l, but arrangedto throw a spray; and Fig. 3, a transverse section through theplug-seat, the plug being removed.

Similar letters denote like parts in the scv eral gures of the drawings.

A is the hollow body of the nozzle, screwthreaded at B for attachment tothe hose,`and

4o provided with a tapered two-way plug, C, transverse to the length ofthe nozzle. Above this plug, and arranged axially with respect to thebody of the nozzle, is the jet-pipe D. Near its outer end the jet-pipeis slightly contracted, so as to leave at its extremity a head, E, andthe outward opening of the body of the nozzle is choked at the sametransverse plane as the contracted portion of the jet-pipe, from whichpoint it flares outward to its extreme end F. Leading from 5o the plug,and arranged one on either side of the entrance to the jet-pipe, are twoopenings,

ai, into the body of the nozzle outside of the jet-pipe. The taperedtwo-way plug is hollow, and has the way b upon one side central 5 5 asto its length, and upon the other the ways c, each a little to one sideof the center. Entrance of water from the lower end of the nozzle-bodythrough the lower wall of the seat is effected by a way, d, as long asthe two C ways c and the distance between them. The plug is secured inthe seat in any suitable manner, as by a washer and screw tapped intothe end of the plug.

The operation of my improvement is as follows: IVhen it is desired toproject ajet of water, the plug is turned to the position seen in Fig. lThe water will then in its passage enter the plug through ways d and c,and pass outward to the jet-pipe through the way 7C b, which correspondswith the rear end of said pipe. The passage of the stream when divergingspray is desired (see Fig. 2) is through ways d and b into the plug,thence to the body of the nozzle outside lthe jet-pipe through ways cand a, and finally outward through the annular orifice betweenthe headof the jet-pipe and the choked end of the nozzle-body. It will thusreadily be seen that the change from solid jet to diverging spray may beeffected by simply reversing the plug in its seat.

I am well aware that nozzles adapted to throw either solid stream or tobe used as a sprinkler have heretofore been made, and I do not wish tobe understood as laying claim, broadly, to this idea. Neither do Idesire to be understood as claiming the use of a two or more way cock toeffect the divergence of the I know to have been done. described myinvention, what secure by Letstream, for this Having thus I claim asnew, and desire to ters Patent, is

l. The combination, with the hollow body of the nozzle choked at itsforward extremity and having the two-way cut-off plug, of the jet-pipearranged axially in the body of the nozzle, contracted and slightlyprotruding beyond its forward opening, whereby asmall in a solid streamor around the latter and out 1o annular exit is left for the escape ofthe water in diverging spray, substantially as set forth. around thejet-pipe, substantially as specified.
